MUSIC-BOX ATTACHMENT FOR CLOCKS.

SPECIFICATION forming part of Letters Patent No. 514,470, dated February 13, 1894.

Application file d April l 9, l 8 93.

To a/ZZ whom t may concern:

Be it known that I, CHARLES H. JACOT, residing at Stapleton, Rich mond county, Staten Island,NeW York, have invented an Improvement in Music-BX Attachments for Clocks, of which the following is a specification, reference being had to the accompanying drawings, forming part hereof, wherein- Figure l is a rear vieu7 of my improved musicbox attachment for clocks, with parts broken away. Fig. 2 is atop vienT of the same, the plunger-rod and hammer being omitted. Fig. 3 is a sectional view on the line 3-3 of Fig. 2 looking in the direction of the arrow. Fig. 4 is a detail plan view with parts removed showing the arm 3 of the tripping lever held out of engagement by the locking lever D. Fig. 5 is a side view of the same. Fig. (i is a similar View to that shown in Fig. t except that the parts are shownin different positions.

' Fig. 7 is a side view of the same.

This invention relates to music-box attachments for clocks, the obj ect thereof being to provide mechanism operated by the clocks movement which will cause the instrument to be played at predetermined intervals, say for instance, each time the clock records an hour, as at nine, ten, eleven oclock, Sac.; and said invention consists in the 'arrangement and combination of parts hereinafter described and claimed.

My invention is an improvement upon the construction shown and described in Letters Patent No. 203,096, dated February 5, 1884, to Jacob Schmid.

In the drawings A represents a portion of the clock-case to which my music-box; is attached. It is obvious, however, that the music-box might be attached to a suitable sounding board or other structure.

B designates the music-cylinder for vibrating the tongues, a, and which is movable in a longitudinal. direction on its shaft, and which may be operated by the spring drum O adapted to be Wound in the usual manner.

b indicates a gear-Wheel, which meshes with a gear driven by the spring drum O. From this gear-Wheel o projects a pin c that is adapted to extend. into a hole or aperture in the Serial No. 470,939. (No model.)

cylinder B and prevent the same from turning on its shaft. erture or hole through it, as shown at e.

d represents a locking lever which is pivoted as shown at e, and has a shoulder thereon and an armf at right angles thereto, said armfezitending back in the path of the pin c, for purposes which will be hereinafter described. This locking lever CZ may also be provided With a second arm g adapted to bear against a fixed abutment (such as the spring drum C) to limit the upward movement of the lever arm f, it being understood that the arm f is normally held down by its own Weight.

The music-box is provided With the fly-fan or escapement connection as shown at h, which may be of any suitable form.

D designates a tripping lever which is provided with three arms l, 2 and 3, and is pivoted as shown at Figs. 3 and et. The arm 3 of this tripping lever D has a lug 7e projecting therefrom in a direction transverse to the length of said arm and adapted to be forced into the hole in the gear-wheel Z) for tripping or holding the same. The arm l of the tripping lever D is received in a notch Z of a Weighted lever E which is pivoted as shown at m and has an arm or plate n attached thereto. The arm 2 of the tripping lever D is adapted to be forced into the path of the fly-fan or escapement 7i of the musicbox as shown in Fig.2 for stopping the Inovement thereof, as Will be hereinafter more fully described. Supported upon the arm or plate 'n of the Weighted lever E is a plunger rod o, prevented from lateral play by suit--` able means, as by the bracket p. This rod o is normally held in an elevated position on the plate n by the Weight on the opposite end of the lever E which overcomes the Weight of the plunger-rod. A lever F is pivoted as shown at 7 and provided with a hammer r thereon, which hammer, when the lever is lowered, is adapted to bear upon or strike the plunger rod o. The shaft s of the minutehand is provided with a pin t or other suitable means for raising the lever F and allowing it to drop when the notch u therein is reached.

The Wheel?) also has an apv Having described the details of my improved music-box attachments for clocks, l will now proceed to describe the operation thereof. The shaft s of the minute-hand being caused to rotate in the direction of the arrow, Fig. l, by the clocks movement (not shown), brings the pin t thereof in engagement with andl raises the lever F until said pin reaches the notch u therein, when the lever F is allowed to drop, causing the hammer r to force down the plunger-rode and the plate end n of the lever E. This causes arrn 1 of the lever D to be forced over, Withdrawing the lug lo on the arm 3, from the aperture z in the gear-Wheel b and withdrawing the arm 2 out of the path of the escapement. When the lug 7c on the arm 3 is withdrawn from the aperture z in the wheel b as described, the lever d drops and the shoulder w thereony prevents the arm 3 from being forced back by the weighted lever E, and prevents the lug la from again locking the wheel b, as shown in Figs. 4 land 5. When, however, the pin c on the wheel b reaches contact with the arm f of the locking lever d, it raises said lever and allows the shoulder thereon to release the arm 3of the tripping lever D, which again forces the lug 7a over into the path of the aperture z, as shown in Figs. 6 and 7, and When said aperture is reached the lug 7c is forced therein and the arm 2 is forced overin the path of escapement h, by means of the weighted lever E, thus stopping and preventing further movement of the music-box until the plunger-rod o is again forced down as heretofore described.

Having described my invention, what I l. The combination with a music cylinder and its escapement of a lever D having an arm 3, locking lever d adapted to lock lever D Weighted lever E connected with said lever D, and means substantially as described for operating it at predetermined intervals, as and for the purposes set forth.

2. The combination with a music cylinder of a tripping lever D, locking lever d adapted to lock said tripping lever, weighted lever E connected to the tripping lever, means substantially as described for operating weighted lever E at predetermined intervals, substantially as and for the purpose herein shown and described.

3. The combination with a music cylinder of a tripping lever D, locking lever d having a releasing arm f, said lever d being adapted to lock the tripping lever, means for engaging said releasing arm f, Weighted lever E connected with said tripping lever, and means substantially as described for operating said weighted lever, substantially as and for the purpose specified.

4. The combination of lever F having notch u therein and hammer r, shaft s having pint for operating said lever, and plunger-rod o normally heldin an elevated position by a weighted lever E, tripping lever D connected with said weight-ed lever, and locking lever d adapted to lock said tripping lever, substantially as described and for the Apurposes set forth.

5. The combination of a music-cylinder B, gear b, having aperture z therein, pin c for uniting said gear and cylinder, locking lever d having releasing arm f, tripping lever D adapted to be locked by said locking lever and having lug 7o adapted to protrude in the aperture .z of gear b, weighted lever E con nected to said tripping lever, and means substantially as described for operating said Weighted lever, substantially as and for the purpose set forth.
